To all whom t may concern:

Be it known that I, HENRY Gr.y VoIGHT, a

citizen of the United States of America, yre-l siding at New Haven, New Haven County, Connecticut, have invented a new and useful jLocking Device for Tire Carriers, of which Vthe following is a specication.

The mainl object of my invention is to provide a simple but reliable and compact Vthe cylinder is `controlled by a spring pressed l latch carried by the cylinder, which in turn is adapted to be retracted by the rotation of a key plug and key. Provision is also made for yieldingly holding the cylinder and latch in the unbolted position so that the key may be withdrawn if desired, and'thevbolt operated by hand to re-lock the parts.

Figure 1 is a perspective view` of the rear end of a vehicle with a tire carrier and 'locking device embodying my'invention. l

Fig. 2 is aplan view and partial'horizontal section of the parts of the locking device.

Fig. 3 is a rear view andvertical section showing the parts 1n their unlockedposition. Fig. 4 is a transverse vertical sectional .view on the plane of the line 4-'4v of Fig. 3.

,'I have shown the device as applied to a ltire carrier of my invention, but it should be understood that the present invention is In the form shown, the bar 5 is supported by brackets 6-:6v and 7.-7 from a suitable support such as another tire carrier rim 8. The ends of the bracket 7 7 are flared outwardly to hold the tire rim in place. Gripping Yjaws 10-'10 are hinged to the4 lower ends of the bar 5, and in turn hinged to toggle bars 11-12 which are pivoted to each other at 13. One of the bars is provided with a stop 14, and the other with a shoulder 15 to limit the downward swing of the parts into their locked'position. Y v

The lock'cylinder 16 is mounted inthe toggle bar 12 and adapted to V reciprocate through thel same horizontally.l A hub` 17 l may be provided for giving additional bearing tothe cylinder. This cylinder is prevented from rotating by a set screw 18, the inner end of which projects into the slot 19 in the cylinder. This also limits vthe transverse motionj of the cylinder with` reference to the bar 12. T'he'other toggle bar is,v provided with a recess 2O and may have a socket member 21 to extend the recess andprovide a coverv or closure. for the end ofthe cylin- Y der '16. Vhen I' use the term cylinder, it should be understood that the cross-sectional shape isimmaterial, but ,Ihave used this term as the one commonly employed to designate the housing or body of a lock of this .type' It willbe seenthat when theinner end of the cylinder is projected into the recess 20, the two parts of the toggleare y positively locked together, but that when the cylinder is drawn out into the position shown in Fig. .4, the toggle members are `free to be operated so 'as to release the jaws 10-10. The cylinder carriesa transversely operable latch member 22 which is preferably pressed by -a spring 23 and engages in a notch 24 at one side of the recess 20 vin the toggle bar 11; Whe-n the parts are in the po' sition-'as shown in Fig. 2.this latch 22 prevents the cylinder, 16 from being pulled outwardly, and thus prevents the unlocking,

of the toggle bars. rlhetoggle bar 12 is also providedI with a recess 25'to receive vthe end of the latch 22 kwhen the cylinder 16 is drawn outwardly. The inclined shoulder 26 serves-to retract the latch-*22 ywhen the cylinder is' pushed inwardly aga-in. The key Aplug 27 isY rotatable in the cylinder 16 by means of a key 28 in the usual manner.

Any` number of pins 29fmay beemployed as .customary in pin tumbler or cylinder locks.

Therear end of the plug 27 is provided .with

- member 30 for retracting the latch' 22 when Vltheplug is rotated. I

The roperation of the device is as follows:

When the partsare in the locked position o-f Fig. 2, the 'key'V is inserted in the plug 27 and rotated sof as togretract the latch bolt22 Vfrom therecess The cylinder body-'16 is thendrawn loutwardly by pullingy upon and limiting its outward movement. When the key is withdrawn from Vthe plug, the spring 23 pushes the latch bolt 22 into the "thevkey intotheposition of Fig. 4, the set screw 18 preventing rotation of the body 16- TGCGSS 95'and the fftogglebars 11 and 121::

may then be operated to release the jaws 10. When the parts are again to lbe loclred position, the toggle bars are straightened out into the position shown in Fig. 1, and it is necessary merely to press upon the cylinder body 16 to push it into the position @f Fg.

2, the latch bolt 22 sliding along the inclined shoulder 26 and snapping out again into the recess 2e.

It will beseen that'the partsL4 are compact and' easily operated to unlo'cl; or lock the device, and also that there are no loose parts or members to be mislai'd, lost, or stolen.
